'The doctrine of the Church of England is gounded in the holy Scriptures, and in such teachings of the ancient Fathers and Councils of the Church as are agreeable to the said Scriptures. In particular such doctrine is to be found in the Thirty-nine Articles of Religion, the Book of Common Prayer, and the Ordinal.' Canon A5

The BCP is included in these pages under the heading of Doctrine because it is part of the "formularies" of the Church of England. This fact is striking in itself because the Doctrine of the Church is not defined simply by docrtrinal statements but also by its liturgy.
